TC Triumph barrel rust

[paul.eshelman]

Hello all. I have a TC Triumph that has a decent amount of rust at both ends and throughout the I interior of the barrel. It is from three years of sitting in the safe and not being super clean when put away (I know shame on me). Just curious if anyone has any recommendations on possible cleaning solutions. I haven't seen any pitting in the barrel. TIA

Put some pb blaster on the rusty area, run a brass brush through then switch to a steel tornado style for the thicker areas.
